CrossFit calls itself the definitive test of fitness, and labels its champions the fittest on Earth. The title proved too tempting for Ricky Garard, 23, who has been stripped of his bronze medal from the 2017 CrossFit Games after testing positive for banned substances.

Australian Garard is the most high-profile CrossFit athlete to have failed a dope test. He must return his US$76,000 prize money and is banned from competing in CrossFit sanctioned events until 2021.

Patrick Vellner was promoted to third place. Two other competitors, in the men’s and women’s masters events, also failed dope tests.

Testolone, and a beta-2 agonist known as endurobol, both anabolic agents, were found in Garard’s samples.

Justin Bergh, general manager of the CrossFit Games, said: “Historically, the most frequent causes for a failed test have been masters athletes failing to read and accept our policy for hormone replacement in competition, and individual and team athletes using supplements containing banned substances not found on labels.”
